### Description of PR JIRA: https://issues.apache.org/jira/browse/HADOOP-20061 `hadoop fs -count -e file:///tmp` fails with `-count: Fatal internal error` and a `NullPointerException` from `ContentSummary#toErasureCodingPolicy`. The same happens on s3a, abfs, viewfs internal directories and WebHDFS against servers older than 3.3.0, where the content summary has no erasure coding policy. The NPE is not an `IOException`, so `FsShell` prints a stack trace and skips the remaining paths. `ls -e` had the same NPE, and HDFS-13661 made it report `FileSystem X does not support Erasure Coding`. This patch makes `Count#processPath` report the same message as an `IOException`, so the error is printed for that path, the other paths are still processed, and the command exits with 1. `FileSystemShell.md` now describes this. ### How was this patch tested? Added `TestCount#processPathECPolicyNotSupported`: `-e` on a file system whose content summary has no policy throws `IOException` with that message and prints nothing. Without the fix it fails with the NPE. ### For code changes: - [x] Does the title of this PR start with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
